Requirement

Python

Pymatgen

We use pymatgen in order to handle crystal structures on your computer.

If you have pip, you can install pymatgen as follows:

> pip install --user pymatgen

Usage

First, you must read structure file from "cif", "poscar", "pymatgen.Structure" or many other structural format which can be handle in pymatgen package as follows:

> from REA import RandomExchangeAtoms as rea

> rea_object = rea("./sample_input/cif/Al2O3_hR30_R-3c_167.cif", format="cif")

If you want to exchange atoms randomly, you can use run_exchange(number) method where number is integer which means number of exchange.

rea_object.run_exchange(5)

If you also think to change cell shape, you can use modify_cell_size() method.

rea_object.modify_cell_size()

In order to export your newly structure, you should call export_dict(filename) method.

rea_object.export_dict(filename="new_structure")

In the default setting export data is the POSCAR (VASP) format.
